China DOS Union

I downloaded a Dwarf boot disk a few days ago. When I extracted the files inside, there was an argj.exe. At first glance, I thought it was a RAR compression, but after adding a few files myself, it didn't work. After testing for a long time, I found that the compression format of this argj.exe was incorrect. The original argj.exe would decompress directly under DOS, but the one I made with RAR wouldn't. And the original argj.exe has the following sentences in the header

It decompresses itself under DOS. I saved the decompression process, please see

Old versions under DOS could be compressed!
I haven't used this, not familiar!

I don't understand...... Which version is needed

This is a WinRAR format DOS self-extracting file.

I don't know how to modify argj.exe of the Dwarf Boot Disk. After I added it, it can't boot.

Using IMG8.0 to modify the dwarf's IMG image file format, then you can use GRUB to load the image and boot! The specific modification format is: System file: F12/16 is also okay, sectors per cluster: 4 (2048), total number of sectors: 12800, FAT12/16 root entries: 224 0XE0, media descriptor: 248 0xf8, sectors per track: 32 0x20, heads: 64 0x40. If you don't know exactly how to do it, you can try it yourself... If you need the format, I can send one.. This format is only for loading a 6.4M image, which is large enough. Many can add many bootings...

Replace it with a self-extracting archive created with RAR version below 2.9 or ARJ version above 2.61

Root of FAT12/16 ...

This way of doing it doesn't work. Even Ms dos can't start anymore

This way of making still can't boot. The size of the made argj.exe is different from the original one. The original is 4.44m while the one compressed by RAR 2.8 is 4.56m, and it can't boot the argj.exe. Entering DOS shows "bad command...".

In addition, I used RAR 2.8 to open the original argj.exe and it shows:

! argj.scr: The file header of "argj.scr" is damaged
! BATCH: The file header of "BATCH" is damaged
! DATA: The file header of "DATA" is damaged

Please give me some pointers

You don't run argj.exe, change to run your own self-extracting package

I extracted argj.exe and then compressed it back into argj.exe. The size changed, it became larger than the original, and it can't run now.

After extracting argj.exe and then compressing it back into argj.exe, the size has changed, it has become larger than the original, and it cannot run
